dit? /d pressed closely against one otl its sides byone or the other ofthe springs .fr .1', until the iinger passes the edge of the plate, whenit is forced sidewise by the spring, and so brought across the edge, tothe opposite side ot' the plate. rldhe sidewise movement of the lingercauses, through the arms L, a sui'licient turn of the sliat't E to throwott' from the screw-shaft the arm 71, till their engaged therewith, andbring the other arm against the opposite screw.

ltwill be readily seen that the operation is now reversed, and willcontinue thus to alter- .nate as long as the machine is kept moving. Theguide -bar B, resting lightly upon the spools, is carried upward by eachsucceeding layer of thread as the spools till, drawing up the arm C, sothat the bar R may be pushed up, and carry with it the plate M, whosebroader portion is thus presented for the tinger to travel around, andthe layers ot' twist be thus gradually increased in length to correspondwith the iiarin g shape et' the spools. The sides of the plate )lcorrespond wita i'onr regular sizes of spools, and the finger 7J beingwider at one end than at the other, and also reversible, eight differentsizes ot' spools may be wound with these devices.

Upon the upper surface of the bracket Q. is arranged a ratchet-wheel, X,whose teeth are, one at a time, directly in the path ot' the tin ger l;as it moves around the plate M, so that the wheel is moved onetooth-each time two lay ers of thread are put upon the spools. Justinside ot' the toothed edge ot' the wheel is a row of perfor-ations, onehole for each tooth. lins p are adjusted in these holes, so that at anydesired portion of a revolution one ot' said pins may strike the arm q,and thereby throw the pawl I out ot' engagement with the wheel, whichthen tlies back to the startingpoint, being` carried back by the springo, Fig. 5, which is t'or that purpose.

It is obvious that a certain number ot' teeth ot' the wheel X may bearranged to represent exactly the number ot' layers required to till aspool, and, it' a pin be inserted to strike the arln q, and also projectthrough the wheel, as p is shown in dotted lines, Fig. 3, so as tostrike the tail ot' the bell-hammer m, not only will the ratchet-wheelbe returned to its starting-point, but the alarm-bell sounded to callattention to the tact thatthe spools are t'ull.

I will now describe my devices which are used for spooling tailors7twist in the fancy or plaited style, which ditfers from the plainspooling in that, instead ot' the threads, singly or several together,bein g wound close together and directly around the spool, the coils areinclined lirst one way and then the other, crossing each other back andforth the length ot` the spool.

' Upon the front end of the platform Y is a post, I, over the top ofwhich tits the end ot' maar@ the arm ll, which is prevented fromslipping oitl bythe nut D. This arm projects directly over the wheel Cr,which has the caingroove in its periphery, and into this grooveprojects, from the under side of the arm, a stud or pin. ln the end ofthe arm H, which extends beyond the wheel, is a slot, and into this slotlits the bent end ot' an arm, K', which is rigidly attached to theguide-shaft E 5 but these two arms, l( and H, are only connected when itis desired to spool tailors7 twist in the plaited style, and at suchtime the plate M is lowered out ot' the ay, as it is not then required,and the arms z h are secured from contact with the screw-threadedsha'l't.

Six, more or less, bobbins being now placed upon the vertical rods oneach side of the machine, and their threads joined and led through theeyes A and the grooved guidebar B, and started upon the spools, and themachine set in motion, the operation is as follows: rllie turning ot'the cam-grooved wheel G causes the arin H to vibrate quickly, and thisarin, through its connection with the arm K, rigidly attached to shaltE, shifts the shalt in and out, and with it the guide -bar l5, throughthe groove in which the twist passes on to the spools, as will bereadily seen, in diagonal coils, which cross each other at acute anglesback and fort-h.

By taking oit' the arm ll, raising the guideplate M, and properlyadjusting the arms 71, the machine is placed in condition todo plainspooling.

My arrangement for grooving the bar D consists in ruiming an einerythread over it from a bobbin to a spool on one ot' the spindles, thespool being large it' it is desired to cut rapidly, and small itlslowly.

llaving thus described my invention, Vl claiml. rl`he combination ol'arm lt, spring l, plate ll', and guiding devices, substantially asspecified.

2. The cam-grooved wheel (ci, arm llf with its stud, arm l', and shai'tl, supporting the guide-bar l, substantially as shown and dcscribed.

3. A spooling-macliine, constructed substantially as described, torplain rqiooling tailors twist, and having a plaiting attachment,substantially as settoi-th.

it. The combination ot' the pcrtoratml ratchetwhcel X, pin p, finger lr,and spring-pawl I, having arm g, and they alarm-bell (Y), substantiallyas specified.
